1 Claim.

The invention relates to an interchangeable jewel mounting and more particularly to jewelry settings.

The primary object of the invention is the provision of a setting of this character, wherein an article of jewelry, for example, a finger ring, is so constructed that varying kinds of stones can be conveniently interchanged in the setting so that the same ring can be converted for the wearing of precious or semi-precious stones at the option of the user of the ring, the setting being of novel construction so that when the stone is held therein it will be secure and prevented from accidental release, yet said stone, when desired, can be readily and conveniently removed from the setting for the placement of a new stone or other kind.

Another object of the invention is the provision of a setting of this character, wherein one of the gripping prongs or tines for holding a stone is swingingly arranged so that such stone can be readily released for interchanging purposes and the tine or prong held secure on the mounting of the stone in the ring, so that there is no liability of accidentally losing the stone from the ring when worn upon the finger, or otherwise.

A further object of the invention is the provision of a setting of this character which is extremely simple in its construction, and in the arrangement does not alter or detract from the conventional kind of prong setting, thoroughly reliable and efficient in its purpose, strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention,

and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of a finger ring showing the mounting or setting constructed in accordance with the invention.

Figure 2 is an edge view thereof.

Figure 3 is a view similar to Figure 2, showing the prong latch released for the opening of the setting.

Figure 4 is a view similar to Figure 1, showing the movable prong in open position.

Figure 5 is an enlarged vertical sectional view with the setting in the position as shown in Figure 1.

Figure 6 is a fragmentary vertical transverse sectional view through the setting.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a finger ring formed with a setting or mounting and including the relatively wide opposed stationary side prongs or tines 10 and the opposed relatively narrow stationary and movable prongs or tines 11 and 12, respectively, these, with the tines or prongs 10, clamping firmly in the head a stone 13 which can be readily removed for interchanging or replacement purposes.

The movable tine or prong 12 is formed with a pivot ear 14 received between a pair of pivot cars 15 integrally formed with the ring A, which latter and the ear 14 has fitted therein a transverse pivot 16 so that the said tine or prong 12 is swingingly mounted upon the ring at the proper locality opposite the tine or prong 11 for the secure clamping of the stone 13 in the head, or the release of such stone.

The inner faces of the tines 10, 11 and 12'are formed with seats 17 for the stone 13, as is conventional.

Hinged to the outer side of the swinging tine or prong 12 is a pivotally supported latch 18, the,

pivot 19 therefor being made secure in the tine or prong 12 and located close to one end of said latch. The latch 18 has the reversely beveled ends 20, these coacting with correspondingly beveled undercut keeper shoulders 21 and 22, respectively, in the said ring and tine or prong 12, so that when the latch 18 is swung in alignment with the tine or prong 12 the ends 20 will engage with the shoulders 21 and 22 and thus lock the said tine or prong 12 in clamping position with respect to the stone 13 for cooperation with the other tines 10 and 11 for the secure holding of the stone in the head of the ring A, as will be clearly apparent.

When it is desired to release the stone 13 from the head the latch 18 is swung laterally at right angles to its normal latching position, thus freeing the tine or prong 12 so that the same can be swung outwardly and in this manner opening the head of the ring A to permit the free withdrawal of the stone 13 from said head, thereby permitting substitution, interchanging or replacement of a stone in the head of the ring.

It also wfll be apparentthat by reason of the fact that the stone can be conveniently removed from the head of the ring A such stone and setting can be more conveniently cleaned than if the tines or prongs were integral or stationary and the stone permanently held thereby.

What is claimed is:

In a finger ring, a head thereon having a plurality of opposed prongs and a single pivotally supported prong, a pivot swingingly connecting the pivotally supported prong to the ring, a stone engaged by said prongs, and a latch pivotally supported on the pivoted prong and engageable with the ring to hold said pivoted prong in clamping position with respect to the other prongs.
